:: McLanahan Updates Universal Jaw Crusher Line
McLanahan’s line of Universal Jaw Crushers has undergone a series of design updates. Based on customer feedback and years of applications expertise, these improvements have been engineered to make everything from installation to maintenance a safer, simpler and smarter process.
This new Universal Jaw Crusher design features replaceable upper and lower stationary jaw die clamp plates, which are lighter, making it easier to install, replace and secure the die. Operators no longer have to rely on heavy key wedge or heel plate style sidelines to lock the dies in place. Additionally, all clamp plates are interchangeable if one side or top/bottom experiences more wear.
Universal Jaw Crushers formerly featured long, one-piece sideliners, meaning the entire part needed replaced when a section was worn. Now, there are three cheek plates per side (top, middle and bottom). This allows liners in high wear areas to be replaced independently of other liners.
Maintenance is greatly simplified by the inclusion of several replaceable parts in the new Universal Jaw Crusher design. The barrel liner, which protects the barrel of the pitman from rock impact and scuffing, is replaceable, as is the smash plate, which absorbs impacts, and wears and deforms before the crusher frame/pitman, prolonging the life of the frame/pitman. In an effort to combat pitman toe wear that can lead to needing a new pitman or extensive pitman toe rework, the new Universal Jaw Crusher design features a bolt-in pitman toe for easy replacement.
When performing maintenance, the new self-aligning locking wedges are adjusted from the rear of the crusher. This area is usually allotted the most space for maintenance and operators don’t have to work around drive guards. Universal Jaw Crushers now come equipped with a safety pin that will lock the pitman in a closed position when maintenance is being performed.
Finally, Universal Jaw Crushers are now designed with frames that are engineered to allow for infinite possibilities when it comes to mounting feet design and customization. With custom feet, the crusher can be tipped forward, as well as located higher and lower or forward and backward from obstructions in an existing or new structure that would have normally made installation impossible.
